IBS: Intelligent battery sensor

The intelligent battery sensor (IBS) is a mechatronic component with its own microprocessor which monitors the battery condition. The IBS continuously measures the following values on the battery:

• Voltage
• Charge and discharge current
• Battery temperature

The IBS is connected with the engine control unit via a local interconnect network bus (LIN bus) for data transfer.

The IBS is installed in the battery in the case of the 12 V lithium ion battery.
